Chauvierre Visiodyne Baby

60 line experimental set used by universities and for research. It had
only 8 tubes. The Visiodyne was built by French TV pioneer Marc
Chauvierre. He was an early adopter of new technology and tinkered a
lot. The Visiodyne was sold as a kit, very few were made as there was
not much to watch back then and the French kept changing their lines
standards, so the major electronics manufacturers decided to wait until
a line standard was set upon before manufacturing in any quantity. The
war interrupted the process before anything was decided, hence the
unbelieveable scarcity of true pre-war French electronic sets.

The museum has a CRT for this set in its
collection. Here is a replica made by French collector Collector André Chompret.
